  The European Spallation Source (ESS), currently under construction and initial commissioning in Lund, Sweden, will be the brightest spallation neutron source in the world, when its driving proton linac achieves the design power of 5 MW at 2 GeV. Such a high power requires production, efficient acceleration, and almost no-loss transport of a high current beam, thus making design and beam commissioning of this machine challenging. The commissioning runs of 2021 and early 2022 were the first where the master timing system for the linac was fully available. As a consequence of that, the beam actuators and beam monitoring equipment relied fully on timing events sent accross the machine, not only to be triggered to act but also to get the configuration. In this paper, we describe the timing system as available today, present how we define and create the beam pulses using the available parameters. We also present planned future upgrades and other outlook for the system.
